Toss the battery and forget about using the VTVM as an ohm meter.  Use
it to measure voltage which is what it is good for with it's minimal
loading high Z. and use a modern DMM for resistors.

> I acquired at a local hamfest last weekend a BEAUTIFUL heathkit IM-11 VTVM. It works well on ac and dc scales but would not calibrate on Ohms.   Looking at the back I noticed discoloring around the screw that holds the C Cell battery spring so I knew what I would find when I cracked it open, and oh yes.. a melted D Cell battery.
